Journal ArticleDOI
Characterization of charge separation in the Array of Micromachined UltraSonic Electrospray (AMUSE) ion source for mass spectrometry.
TL;DR: It has been demonstrated, through a number of electrode/electrical potential configurations, that increasing charge separation leads to improvement in signal abundance, signal-to-noise ratio, and signal stability.
Journal ArticleDOI
A Power-Efficient Bridge Readout Circuit for Implantable, Wearable, and IoT Applications
TL;DR: A power-efficient bridge-to-digital sensing interface is proposed, which also offers immunity against power supply noise and uses a revised version of the pseudo-pseudo differential (PPD) topology with the ping-pong technique to reduce the complexity of traditional fully-differential counterparts.
Journal ArticleDOI
In situ ultrasonic measurement of photoresist glass transition temperature
TL;DR: In this paper, the phase of a high frequency ultrasound signal was monitored as it was reflected from the silicon/photoresist interface during photoresist prebake, and the glass transition temperature (Tg) for a freshly spun 2.2 μm Shipley 1813 resist was measured to be 50
Proceedings ArticleDOI
Evaluation of CMUT annular arrays for side-looking IVUS
Alper Sisman,Jaime Zahorian,Gokce Gurun,Mustafa Karaman,M. Balantekin,F. Levent Degertekin,Paul Hasler +6 more
TL;DR: In this paper, the authors explore a new SL-IVUS probe architecture employing rotating phased annular CMUT arrays and compare the imaging performance of the existing and proposed probe configurations through simulated point spread functions.
Journal ArticleDOI
Capacitive micromachined ultrasonic transducer arrays as tunable acoustic metamaterials
TL;DR: The dispersion and tunability characteristics are examined using a computationally efficient, mutual radiation impedance based approach to model a finite-size array and realistic parameters of variation.
